" TRIPOD.

SPECIFICATION forming part of Letters Patent No. 791,689, dated. June 6,1905. Application filed March 21,1905. Serial No. 251,349.

To all whom, it worry concern:

Be'it known that 1, JAMES L. G LMORE, a citizen of the United States,residing at Leroy, in

the county of Coffey and State of Kansas, have invented certain new anduseful Improvements inTripods; and I do hereby declare the following tobe a full, clear, and exact description of the invention, such'as willenable others skilled in the art to which it appertains to make and usethe same.

This invention relates to tripods for supporting loads, and moreparticularly for use in supporting the sickle-barof a harvester whilebeing ground to resharpen the cutting edges; and it consists in thenovel construction and combination of the parts hereinafter fullydescribed and claimed.

In the drawings, Figure l is a side view of the tripod. Fig. 2 is a planview of the tripod. Fig. 3 is a detail end view of the two short legs ofthe tripod.

The tripod is provided with a longlegA in front and two shorter legs Bat its rear part. The upper ends of the legs B are fitted against theupper portion of the leg A, and 5 represents eyes or other equivalentcoupling devices, which secure the upper portions of all three legstogether and which permit the legs to be folded together, so that theycan conveniently be moved from place toplace. The lower ends of the legsare preferably pointed, so as'to engage with the ground. When the tripodis set up, a hook G, pivoted to an eye 0 on one of the legs B, engageswith an eye D on the other leg B and prevents the rear legs B fromspreading. E is a flexible connection between an eye a on the front legA and the said eyes 0 and D on the rear legs.

F is a flexible connection having its ends secured to the lower parts ofthe two rear legs B and provided with a guide-loop f at its middle part.I

G is an arm, the middle part of which is pivoted upon a substantiallyvertical pin 9, which projects from a shoe H, so that the said arm isfree to move in a substantially'horizontal plane. The shoe H is pivotedto the upper end of the long leg A by'a pin it, so that it and the arm Gare free to move to a limited extent in a vertical plane. .A ring I isproproved winding barrel, shaft, or peg.

vided at one end of-the arm G for the attachment of a sling or othersimilar supporting device, which is attached to the sickle-bar of theharvester when removed from the machine.

J is a cord or other flexible connection which is attached to the otherend of the arm G by means of a spring a and a ring j. This cord ispassed through the guide-loop f and through a guiding-eye 7:: on thelower part of the leg A and is connected to' an adjusting device K,which is also carried by the leg A.

The adjusting device K consists of any ap- The end portion of the cordis wound upon this adjustingdevice, and the ad usting device is revolvedby hand to adjust the length of the cord and the inclination of the armG. When awind'ing-barrel is provided for use as an adjusting device, thearm Gr can be used as a derrick for raising weights, as well as forsupporting a sickle-bar.

The spring i permits the sickle-bar to be I dinally-extensible springconnection between one end of the said arm and one of the said legs.

2. The combination, with an upwardly and rearwardly inclined front leg,and two rear legs supporting the said front leg; of a supporting-armpivotally connected with the top of the said frontleg and movablehorizontally and vertically, and'a longitudinally-extensible springconnection between the rear end of the said arm and the lower and frontend portion of the said front leg.

3. The combination, with one long leg, and two shorter legs having theirupper end portions pivoted together; of a flexible connec-' 'tionbetween the long leg and the two shorter legs, a rigid connectionbetween the said shorter legs, a supporting-arm pivotally connected withthe top of the long leg and movable horizontally and vertically, and aspring secured to one end of the said arm and passconnection between oneend of the said arm ing through the said guides and connected to and thesaid long leg. the said winding mechanism.
